25 Nm sustained

Specified sustained torque from the direct-drive motor.

21-bit magnetic encoder (2,097,152 PPR)

The verified encoder resolution for precise position sensing.

True Torque sensor

0.1% measurement accuracy, up to 2 kHz sampling rate.

MOZA R25 Ultra True Torque is MOZA's most powerful direct drive wheelbase, developed for professional and advanced sim racing. Its new zero-cogging flat-wire motor delivers 25 Nm of sustained torque with smooth response during long endurance sessions.

A built-in True Torque sensor measures the wheelbase's actual output torque with 0.1% accuracy and a sampling rate of up to 2 kHz. Combined with a 21-bit magnetic encoder with 2,097,152 measurement points per revolution, it provides fast, detailed feedback from subtle steering signals to heavy loads.

MOZA's new force feedback algorithm, iRacing 360 Hz support and intelligent thermal management provide consistent performance. The CNC-machined aluminium housing features dual RGB light strips with telemetry-driven effects and is configured through MOZA Pit House or the MOZA Racing app.

R25 Ultra supports bottom, front and side mounting using the Ultra's own hole pattern. Mounts designed for the R21 V2 or older R16/R21 models must not be assumed compatible.
